Hard mode forces you to use letters that you already uncovered. A lot of people play that way normally so you don't see a difference, however it prevents you from throwing out random guesses for the sole purpose of eliminating letters. For example, when the Worlde was 'Light' a few days ago, if you had revealed _IGHT, you might not know if the word is Light, Tight, Sight, Right, Night, etc. On Normal Mode, you can throw out a word like TRANS to eliminate many of those possibilities. On Hard Mode, you can't since you're forced to use I G H and T.
